Hw-417-v1.2 Driver Jun 2026

: Most modern kernels (Ubuntu 11.10+) have the FTDI driver pre-installed. 3. Installation Guide (Windows)

Standard pins include DTR (for auto-reset), RX, TX, VCC, CTS, and GND. Where to Download the Driver

Before discussing the driver, it is critical to understand what the HW-417-V1.2 hardware is. Based on common PCB markings and component layouts, the HW-417-V1.2 is typically one of two modules:

Look for , where x represents the assigned port number (e.g., COM3). 2. macOS Installation hw-417-v1.2 driver

Linux and macOS offer native support for the FT232RL chip, typically requiring no manual driver installation. The system should automatically recognize and configure the device. On macOS, the device will likely appear under /dev/cu.usbserial-XXXX . However, for macOS users (especially on Apple Silicon M1/M2), it is best to keep the operating system updated to ensure full compatibility, as Apple’s driver implementation has undergone changes.

. For most users, the "setup executable" is the easiest option as it automatically installs both VCP and D2XX drivers. Installation Run the downloaded file (e.g., CDM21228_Setup.exe Follow the prompts to extract and install the files.

Despite the "HW-417" label on the PCB, the magic happens inside the small black chip on the board. In 99% of cases, this board uses the or CH340E chip. : Most modern kernels (Ubuntu 11

Download the CH341SER_MAC.ZIP driver from the WCH website.

: If the automatic install fails, right-click the "offending" device, select "Update Driver," and point the wizard to the folder where you unzipped the FTDI drivers. 4. Important Hardware Settings HW-417-V1.2

Connect your HW-417 module to your computer via USB. Windows should now automatically assign it a COM port. Verification : Open the Device Manager Where to Download the Driver Before discussing the

Most users interface HW-417-V1.2 with an Arduino board. In this case, the driver is the and the CH340/CH341 USB-to-Serial driver (if using a clone board).

: Modern versions (Big Sur and later) generally have built-in support for FTDI chips and may not require a manual download.

: Many HW-417 modules use non-genuine FT232RL chips. Modern FTDI drivers may "brick" these chips or refuse to work with them (showing a "Code 10" error).
